Abstract
The risk of female breast cancer in association with radiation exposure is well established, on the basis of follow-up studies of the atomic-bomb survivors and other exposed populations. This association is especially strong for women exposed before age 20 yr and appears to be much weaker among women exposed after age 40 yr. In this study, breast-tissue autopsy samples from high-dose and low-dose individuals in the Radiation Effects Research Foundation Life Span Study sample were examined in detail to determine whether nonproliferative or proliferative breast lesions are associated with radiation exposure. The results suggest that proliferative disease in general and atypical hyperplasia in particular are associated with radiation exposure and that the risk is strongest for subjects who were ages 40-49 yr at the time of the bombings. It is hypothesized that this finding may be related to the age dependence of radiation-induced breast cancer, in the sense that potential cancers reflecting early-stage changes induced at these ages by radiation exposure may receive too little hormonal promotion to progress to frank cancers.
